Background: Nurses, as the largest group of health professionals, have a key role in recognising, mitigating and preventing domestic violence. However, studies demonstrating effective undergraduate educational interventions are lacking. The research aim was to compare undergraduate nursing students’ knowledge and attitudes about domestic violence before and after an educational intervention on domestic violence and explore their views on the most useful teaching strategies. Methods: A quasi-experimental pre and post design was used to determine the impact of an educational intervention. Australian nursing students enrolled in a first-year undergraduate subject were invited to participate. The educational intervention included a 40-min pre-recorded lecture on domestic violence, and a two-hour face-to-face workshop facilitated by an expert, supported by readings. Students completed a pre- and post-intervention online anonymous survey using a validated instrument, the Inventory on Beliefs and Attitudes towards Domestic Violence. Wilcoxon signed rank tests were used to compare pre and post intervention results. Results: Approximately 400 students completed the voluntary workshop; 198 students completed the pre survey, 176 completed the post survey and 59 (13.1%) completed both. Post intervention, participants indicated stronger agreement on 15 of 22 items. The inventory score became significantly more positive (Z = -3.196, p =.001, CI -.206—-0.067) post intervention. Of the 173 students who indicated post intervention which forms of education they found useful, 38.2% considered face-to-face tutorials to be the most useful education modality. Conclusions: This study demonstrates the effectiveness of even a small educational intervention in changing attitudes, and creating awareness and knowledge of the context, prevalence, perpetrators, and significant associated burden of illness related to domestic violence, and nurses’ responsibility to support victims.
